Roc Nation's Rihanna rocked new single "Bitch Better Have My Money" on the iHeartRadio Music Awards; you can check out her performance at the link below. In the photo above, RiRi is seen with iHeart luminaries Tom Poleman and John Sykes, who helped unload her helicopter from Pittman's jet.

Columbia's Walk Off the Earth have dropped new single "Rule the World" and its attendant video. The tune is the first salvo from the Canadian band's forthcoming sophomore album (due this summer); WOTE begins a North American trek on 5/6. We take no responsibility for the song getting lodged in your skull like a hatchet.

The most talked-about moment at Sunday night’s iHeartRadio Music Awards was the unannounced onstage reunion of ABBA. In this historic post-performance photo, the legendary group is all smiles backstage. We have just one question: Which one’s Bjorn and which one’s Benny?

BIEBER’S PUZZLING RESURFACING

3/31/15

Justin Beiber's return to the live-performance spotlight by way of a headlining spot at the Fusion Festival this August in Birmingham, England—which boasts a less than scintillating talent lineup including Rixton, Rudimental, DJ Fresh, Fuse ODG and McBusted—led some to question the strategy of manager Scooter Braun when it was announced last week. With Bieber’s career at a pivotal point, what value could this second-rate festival date possibly have?

Electric-blues avatar Muddy Waters, a number of his contemporaries and a posse of inheritors mixed it up in live performance 41 years ago for a TV show conceived and produced by then-young pup Ken Ehrlich. Soundstage: Blues Summit in Chicago, coming from Legacy on April 21, marks the first time this historic 1974 episode has been released on DVD.

Team Jay Z chose the first half-hour of The Voice to make their prime-time mainstream play with was a 120-second spot containing documentary-style footage of today's highlights, the vibe very much like the Magna Carta announcement during the 2013 NBA Finals, though this one was more star-studded. Those are the facts; we’re still trying to process the principals’ intent or what the reaction will be. At the very least, the spot should arouse the public’s curiosity about what “product” these stars are trying to sell them.
